This was the first book I read written by Von Mises, when I did it, I did not even know who this man was, then I am very clear who he was, he was the one who finished me becoming a liberal, although I was already one, but without knowing it. Thanks to Von Mises, I truly understood how the economy works in depth. His description of praxeology, and how he delves into it, is incredible. He explains perfectly the impossibility of economic calculation in socialism, among many other things. A very good book that is worth reading. I lent that book to two socialists that I know and with whom I always argue, one did not read it, and another barely started it. Apparently the socialists do not like to read, even less if it is about economy.
